The object of this invention is to provide a very efficient device for holding and turning in or out stove bolts or the like in difficult places. Another object is to considerably improve on the existing regular tools. A further object is to make this tool very simple, very efiicient and very inexpensive.

The accompanying drawing and specifications will fully illustrate and describe the invention. And also, similar numerals and characters refer to similar parts throughout.

In the drawing:

FIGURE 1 is a side view of my invention.

FIGURE 2 is an enlarged view of the top and bottom portions of my invention. It also shows a bolt, sidewise.

FIGURE 3 is an enlarged end view of the top and bottom portions of my invention. It also shows a cross-cut of a bolt.

The drawing shows in detail the tool A, the top 1, the arms 2 and 3, the bottom ends 4 and 5 and the furrows 10. It also shows the bolt 6 with the head 7, the head slot 8 and the threads 9.

As commonly known, stove bolts or the like very often become very diflicult to handle in many places. My invention is adapted to be very useful and very efiicient in these difiicult situations.

Referring to the drawing in detail, my invention is the tool A. The tool A is made of a single length of a round spring wire which is bent back upon itself to form the coil spring top 1 at the top end. The top 1 is adapted to provide a spreading spring pressure.

The two arms 2 and 3 extend downwardly from the said top 1 which serves to keep the arms 2 and 3 separated, when free, resilient and movable when desired.

The ends 4 and 5 are shaped fiat and so formed to fit into the head slot 8 of the bolt 6. These ends 4 and 5 are located at the extreme bottoms of the two arms 2 and 3.

In FIGURE 3 of the drawing, the furrows 10 are shown only on the arm 2. These furrows 10 are made on the outer sides of the two ends 4 and 5 so that the tool A is provided with a considerably improved grip that prevents slipping when inserted into the bolt head slot 8.

As shown in the FIGURES 2 and 3, the movable arms 2 and 3 are manually pressed together, the two aligned ends 4 and 5 are fitted into the bolt slot 8 and the spring top 1 provides a spreading pressure. With this arrangement, the tool A can be very efficiently used to firmly grip and to turn in or out the bolt 6 in regular places and also in places too difiicult for the existing standard tools.

And thus, the tool A is made very simple, very inexpensive and very efficient for all stove bolts or the like. The tool A can be made in many different sizes. As illustrated and described, the tool A represents all tools subject to the very same uses and conditions.

Having described by invention, I hereby make the following claims, substantially as illustrated and described:

1. A screwdriver comprising, a body consisting of a single length of a spring wire bent back upon itself into a circle to form a coil spring at the top end, two resilient arms extending downwardly from the said coil spring top and having fiat-shaped bottom ends, said coil spring top biasing said bottom ends out of a common plane and said bottom ends being adapted to be moved into a common plane so as to be inserted into the head slot of a bolt or screw for holding and turning the same.

2. A screwdriver according to claim 1 in which a coil spring top functions to change the planes of the said two bottom ends so as to form a firm self-locking grip for holding and turning a belt or a screw.
